Abstract (en)
[origin: EP3675276A1] This application provides a dielectric resonator, including a dielectric body disposed in a hollow conductive housing, where the dielectric body includes a first end face and a second end face that are disposed opposite to each other and a circumferential surface connected between the first end face and the second end face, the first end face is provided with a first groove, the second end face is provided with a second groove, the first end face and the second end face are in contact with an inner wall of the conductive housing, and extension directions of the first groove and the second groove are different. This application further provides a filter. This application can implement single-sided installation of the dielectric resonator, so that an objective of miniaturization is achieved and assembly becomes easy. In addition, coupling between resonance modes can be enhanced because the extension directions of the first groove and the second groove are different.
